Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed August 6, 1904:. Serial No 219,758-

- To all whom, it may concern.-

Be it known that I, THOMAS H. JORDAN, of Stamford, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in a Combined Floor- Hinge, Door Check and Closer; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Myinvention relates to an improvement in a combined floor-hinge, doorcheck and closer, and is especially designed for use in connection witha swinging door which is mounted at its lower end upon an actuatingspindle or pivot and held at its upper end by a stud projectingdownwardly into a socket carried by the upper edge of the door or by anyother approved means.

The object of this invention is to provide a construction wherebygreater pressure is required to start the opening movement of the doorthan is required to continue the movement when once started; and myinvention consists in the parts and combinations of parts, as will bemore fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in longitudinalvertical section of my improvement. Fig. 2 isa view in plan, partly insection, the top plates of the casing being removed. Fig. 3 is a view intransverse section on the line A A of Fig. 2. Fig. 1 is a similar viewon the line B B of Fig. 2; and Fig. 5 is a longitudinal sectional viewtaken through the casing, spring box or chamber, and end of piston.

1 represents a rectangular inclosing casing designed to be seated in thefloor beneath the door with its upper surface flush with the sill. Thiscasing is preferably made of a single integral casting open at its topand provided at its sides with horizontal flanges 2, adapted to rest inrecessed seats in the floor or sill. These flanges are provided withcountersunk openings 3 for the passage of screws whicli secure thecasing to the floor and also with threaded openings A for the engagementof screws 5, which secure the cap or face plate 6 in place. This casingis also provided with a series of internal shoulders 7, having threadedopenings therein for the engagement of the screws 8, which secure theinner sectional cover 9 in place.

Located within the casing 1 and near one end of the latter is thecircular box 10, forming a springchamber carrying the coiled spring 11,the inner coil of which is connected to the sleeve 12, located centrallywithin the box 10, while the outer end of the spring is connected to theinner face of the box 10. The sleeve 12 is mounted on the stud 13 andalso on the annular flange 1 1, projecting upwardly from the cover ofsaid box, and is provided at its upper end outside of the box with aratchet-wheel 15, the teeth of which are engaged by the sliding pawl 16,mounted in the inclined seat 17, formed in the sectional cover 9. Thesleeve .12is also provided with an upwardly-projecting annular flange18, which rests within a seat or opening formed in the sectional cover9, the recess embraced or formed by this flange being angular, as shownin Fig. 2, to receive a key or other instrument by which when the cap orface plate 6 is removed the ratchet-wheel can be turned or rotated toadjust the tension of the spring. When, however, the cap or face plateis in place, this angular recess and the pawl 16 are covered, thuslocking the sleeve 12 against any movement. end of spring-chamber 10 isrotatably mounted, is seated in a bearing formed in the floor of thecasing. WVith this construction it will be seen that the box 10, towhich one end of the spring is attached, is free to turn on its axis,while the sleeve 12, which is connected to the inner end of the spring,is normally locked against any movement.

Depending from thebottom of the spring box orchamber 10 and eccentric tothe axis of said box is a stud 19, to which one end of pitman isconnected, the end of the pitman connected to said stud being slightlycurved, as shown in Fig. 2, to permit the stud 19 to normally restnearly on a dead-center or nearly on a line with the center of thecombined hinge and check. The opposite end of pitman 20 is pivotallyconnected to the stud 21 on lever 22. This lever is fulcrumed on thestud 23, carried by the casing 1, and is connected by pin 2 1 and rod 25with piston 26. This piston 26 is mounted in the checking-cylinder 27,which is secured in any suit- Stud 13, on which the lower able' mannerwithin the casing 1, with its closed end adjacent to the box 10. Thechecking-cylinder is provided with an upward eX- tension 28, having acircular flange 29, embracing a corresponding flange 30, depending fromthe inner sectional cover 9. The upper wall of the cylinder is boredout, as at 31, to form a by-pass, and two ports 32 and 33 lead from thisby-pass into the cylinder on opposite sides of the piston, the port 32being located near the closed end of the cylinder, while port 33 is nearthe open end of the latter. 34: is a screw-valve mounted in theextension 28 of the cylinder and projecting up and through the innersectional cover and cap or faceplate 6, so as to be accessible at alltimes. This screw-valve is for regulating and controlling the passage ofthe liquid into and out of the cylinder in front of the piston, the rearend of the cylinder being open.

Connected to the piston 26 and to lever 22 by pin 24 is the slidingframe 35, which latteris mounted at its sides on the flanges or guides36, formed on opposite sides of the cylinder 27. This frame 35 isprovided at its rear end with an open slot 37 and on opposite sides ofthe slot with the studs 38, carrying antifriction-rollers 39.

Mounted in bearings formed in the floor of the casing and in the innersectional cover 9 is the spindle 40. This spindle passes through theslot 37 in frame 35 and projects up above the top of the casing. Itsupper end is made angular to engage a corresponding socket set into thelower edge of a door, and it is provided at a point in line with therollers 39 with the heart-shaped cam 41, which latter is rigidly securedto the spindle and engages and is engaged by said antifriction-rollersand also by the antifriction-roller 42 on pin 24.

Vith the above construction it will be seen that when the door is pushedin a direction to open it the spindle 40 will be turned, thus causingcam 41 to engage one of the antifriction-rollers on sliding frame 35.This engagement of the cam with the roller slides the frame 35rearwardly, which movement of the frame draws piston 26 toward the openend of its cylinder and, through pitman 20, turns the spring box orchamber 10 on its axis. As the piston is moved rearwardly the liquidcontained in the casing passes into the cylinder in front of the pistonthrough the valved port 26 in the piston-head, as shown in Fig. 5, andthe turning movement of the box 10 winds up the spring. Hence when thedoor is released the spring acting through box 10, pitman 20, lever 22,antifriction-rollers 39, cam 41, and spindle 40 immediately closes thedoor, the closing movement, however, being checked by the liquid infront of the piston 26 in the usual and well-known manner. When,however, the door is in its closed position,- the end of the pitmanattached to the box rests nearly on a dead-center or in line with thecenter of the combined closer hinge and check. Hence the power of thespring is multiplied through the levers and exerts a greater force uponthe door when in its closed position than at any other point. After thedoor has been started in its opening movement the leverage increases,thus requiring less power or pressure to complete the opening movement.

It is evident that many slight changes might be resorted to in therelative arrangement of parts herein shown and described withoutdeparting from the spirit and scope of my invention. Hence I would haveit understood that I do not wish to confine myself to the exactconstruction of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a casing,and a spindle carried thereby andadapted for connection with a door, of a spring box or chamber locatedwithin the casing and mounted to turn, a liquid-check also locatedwithin said casing, and means also located within said casing andoperatively connecting the springchamber liquid-check and spindle.
